I have a relatively Google'd Android running lineageOS. It passes SafteyNet on a fresh install, but even that isn't good enough for one of my banking apps (or netflix) - they both also perform a CTS Profile (Compatibility Test Suite) check and block me from using the app if they don't like what they see.
I ultimately had to root the phone to be able to use my bank's app. Rooting allowed me to use a fake CTS Profile, and then because it was rooted, SafteyNet started failing and I had to install a bypass to work around that.
Now everything works great, except OS updates un-root the phone and then "secure" apps stop working again.
(Oh, and if you mention that you're rooted, the LineageOS folks will refuse to provide any support, even for unrelated issues. Making you choose between friendly help and a usable phone is probably the only thing I don't like about LineageOS and, to my view, the biggest break from it's CyanogenMod roots.)
